Other and further important objectsof the presentinvention will be apparent from the disclosures in the following speciication, appended claims and accompanying vdrawing wherein:

Fig. 1 is a sectional view showing vthe oil and water containers utilized in the present invention;

Fig. 2 is an enlarged fragmentary sectional view showing the valve structure in the discharge from a container and method of mixing, and/or combining` air, water,

alcohol and oil, in an atomized gaseous vform for delivery thereafter rto the gaseous stream vissuing from a gasoline Ycarburetor utilized in connection with internal combustion engines. As shown primarily in Fig. l ofthe drawing, a container, indicated generally at 10, Vis adapted to contain the various liquids to be atomized. The container comprises an outer cylindrical jar portion 11,v f having a-closed bottom 12 and threads 13 formed ad Vjacent an upper end 14. The threads 13 are adapted to be engaged by a cap member 15 having internally di- ICC a rected threads 16 formed in a downwardly .directed ange 17. A raised boss 18 is formed axially upwardly from the cap 15, this boss having inwardly directed threads 19 that are adapted to be engaged by threads 20 formed on an internal jar 21. The jar 21 has aplurality of openings 22 adjacent the upper end thereof and a closed bottom portion 23, the bottom portion V23 'being in spaced relationship with respect to the bottom 4portion ,12, and the outer jar 11. The openings 22 provide com.- munication between a chamber 24, formed vin the outer jar 23 intermediate the walls thereof, and the walls of the inner jar 21, and a chamber 25 formed in theinner jar 21. The chamber 24 is sealed from atmosphere by means of a gasket 26 that is disposed intermediate the upper end 14 of the outer jar 11 and the cap `member 15.

The outer jar 11 is fitted with a iiller pipe 27 that makes threaded engagement with the cap member 13, a closure 28 being secured to the upper end of the pipe 27. By thismeans, a combination of water and alcohol or water alone, .as indicated at 29, is adapted to be placed ,in the .chamber 24 intermediate the inner and outer jars. The boss 18 is also fitted with a iller pipe 30 that has a closure 31 on the upper end thereof, so that oil indicated generally at 32 may be placed in the interior of the inner jar 21 and in the chamber 25,. The oil 32 may be of the type for use in upper cylinder lubrication and is of a high heat resistantvariety.

As shown primarily in Eig. 5, the container arrangement 1t) is adapted to be placed in communication with a conventional carburetor 33 as by a iitting 34, positioned intermediate a carburetor flange 35 and the intakemanifold 36 of an internal combustion engine. Communicationintermediate the jar and the fitting 34 is accomplished by means of a conduit or tube 37 that is connected to an exit structure indicated generally at 38, Fig. l. A wick 39 has its lupper end 40 disposed in a tuber 41 of the structure 38 and extends downwardly to the bottom 23 of the innerjar 21. The upper end of the tube y41 extends slightly beyond the upper surface of the boss 18 and is fitted within Athe tube 37. The tube 37 makes a threaded connect'ion as at 42 with the upper wall of the boss "18.

For the admission of air to the present device, an entrance structure indicated generally at 43 is provided. The entrance structure makes threaded connection as at 44 with the upper wall of the cover 13, there being a tube 45 disposed in the lower end of a conduit 46 yforming part of the entrance structure 43. A wick 47 has its upper end 48 disposed in the tube 45 and extends downwardly and across the bottom 12 of the outer jar 1l. As shown in the drawing, the wicks 39 and 47 have thelower portions thereof disposed respectively in the oil 32 and the alcohol/water combination 29.

With reference primarily to Fig. 2 .of the drawing, the exit structure 38 further includes a pair of sleeves 49 and 50 that are retained in spaced relationship within the tube 37 at a point slightlyV downstream from the outer end of the tube 4l and wick 39. Each of the sleeves 49 and 50 has a closed bottom portion 51 in which openings 52 and 53 are formed axially. A pair of impingement members 54 and 55 are disposed in the sleeves 49 and 50 respectively and secured adjacent the bottom walls 51, each of these impingement members presenting an impingement surface 56, the purpose of which will be hereinafter more fully described. The openings 52-and 513 are slightly different in size, the opening 52 being in the nature of .026 inch and the opening 53 being in the nature of .0l6 inch, for example, thesev respective sizes having been found to 'be necessary to accomplish the atomization of the various "liquids in the present invention and to carry out the purpose ofthe invention.

The entrance structure 43 is provided with a pair of sleeves 57 and 53 that are disposed in the tube 46 at a point spaced outwardly from the outer end of the tube 45 and wick 47. Each of the sleeves 57 and 58 is provided with a bottom wall 59, these walls being provided with axially disposed openings 60 and 61. In a manner similar to the structure shown and described in connection with the exit structure 38, the openings 6i) and 61 are of slightly different size with the opening 60 being in the nature of .026 inch and the opening 61 being in the nature of .016 inch for a purpose to be hereinafter more fully described.

As shown primarily in Fig. 4, the wicks 39 and 47 may be provided with a centrally disposed wire 62 or the like in order to stiffen these Wicks and prevent their movement inadvertently from the liquids 29 and 32.

In operation of the present invention, the water and alcohol mixture 29 is adapted to saturate the wick 47 as by capillary action and the oil 32 is adapted to saturate the wick 39 by a similar action. As a reduction in presl sure is created in the manifold 36 of the internal cornbustion engine, a suction will be applied through the tube 37 and a reduction in pressure will thereby exist in the chamber 2S and the chamber 24 by means of the openings 22, thereby to draw air in through the tube 46 in the entrance structure 43. The air being admitted through the tube 46 is atomized through the openings 61 and 60 and `is drawn therethrough as by a jet action to impinge on and through the outer end 4S of the wick 47, thereby to cause an atomization and vaporization of the water/ alcohol mixture contained in the wick 47. This atomized ,liquid thereafter fills the chamber 24 and passes into the chamber 2S by way of the openings 22. In this connection, it is to be understood that portions of the threads 19 and may be removed to provide a connection intermediate the chambers 24 and 25. The suction created through the tube 37 is thereafter adapted to draw the vaporized water and alcohol mixture through the wick 39 and the upper end 40 thereof to pick up vaporized oil particles. These oil particles together with the oil and water mixture are thereafter adapted to pass through the jet or orifice openings 52 and 53 and impinge upon the impingement surfaces 56 formed on the impingement members 54 and S5. The oil/water/ alcohol vapor is thereby completely atomized and mixed together for passage thereafter into the tube 37 and the fitting 34 for use as an induction charge in combination with the gasoline and air being drawn in through the carburetor 33 and into the manifold 36 of an internal combustion engine.

The charge thus produced for combination with the major charge formed in the carburetor 33 of an internal combustion engine is thereby drawn into the manifold thereof to improve combustion and provide continuous means for lubricating the upper cylinders of the engine. It has been found that through the use of the present device, carbon or other collections within the cylinder heads is softened, the cylinder heads are maintained in a cleaner condition, the spark plugs are maintained clean and free from carbon deposits and the valves are kept free and lubricated. The use of the present device further assists in keeping the lubricating oil of the internal combustion engine clean and reduces the operating temperature of the engine thus providing for rapid starting, ideal combustion conditions, efficient performance of the engine and greatly improved gasoline mileage.

In some instances, it may be desirable to provide for only upper cylinder lubrication without the water-alcohol injection. In such instances, the filler pipe may be removed and replaced with the entrance structure 43 together with the wick 47 and tube 46. The pipe 30 together with the closure 31 may thereafter be placed in the threaded opening normally occupied by the entrance structure 43 in the cap l5. In this instance, air is drawn in through the entrance structure 43 atomizing oil that would be contained on the wick 47 and thereafter in a manner similar to that previously described through the upper end of the wick 39 and out through the exit structure 38 to the manifold of the internal combustion engine.

In some instances, it has also been found that additional vaporization by evaporation may be provided by the insertion of additional wicks or cloth members in the various liquids, the upper portions of which are adapted to extend above the upper surfaces of the liquids.

Having thusv described the invention and the present embodiment thereof, it is desired to emphasize the fact that many modifications may be resorted to in a manner limited only by a just interpretation of the following claims.
